Every time a file is accessed the file system updates an internal table
noting the last time it was accessed. Used for tools like find. Most
people don't ever use this data themselves directly.

It should, though there are some apps that don't behave properly without
atime being updated. I don't recall any off the top of my head but recall
discussions over the years where people have mentioned some. Maybe they
are mostly fixed now, I'm sure a google search will turn up results.
